         | like today we only have JPEG like static compressors for
         | meshes.. but this code TVMC does inter-frame compression to
         | exploit temporal redundancy like an mp4. Pretttty cool

           | Oh that is pretty neat, I'm still failing to come up with any
           | current use cases though. Most animations I'm use to are bone
           | based which I think would still be smaller than this. I could
           | see it for vertex based animations, but I'm not sure of any
           | current cases where this is used. I'm sure there are good
           | uses out there, I'm probably just missing it. I can at least
           | think of potential future uses like vr movies, where if it's
           | recorded and reconstructed into a 3d scene the bone
           | information won't be there and most likely won't help even if
           | it was.

             | Most animation in VFX is exported as alembic or USD and
             | generally the skinning/bone deformations are baked down to
             | vertex animations and sent on to the fx, lighting and
             | compositing departments in that simplified but data heavier
             | form. Better compression could save us many terabytes where
             | I work, and who knows how many petabytes across the
             | industry. Most studios use some amount of cloud rendering
             | and the reduction in network traffic and storage with those
             | farms would be appreciated.

       | Curious about benchmarks comparing overhead with other container
       | security approaches.
